What you need.
Plastic container/s that fruit or cakes are sold in
My containers had grapes in. I try to buy unpackaged fruit but these were a gift.
Other containers you can use are often sold with cakes in and have a hinged lid.
Mine have some holes in the bottom so before I fill one with compost I line it with newspaper.
Then fill with moist compost and firm gently, this means tap the compost with your fingers flat, you don’t want it to be solid but also you don’t want big air pockets.
Water your compost if it is a little dry. I use a spray as you don’t want it too wet.
Pour a few seeds from the packet into your palm ready to sow.
Sprinkle the seeds all over the compost. These can be quite close as you will prick them out once they have a real leaf.
Cover your seeds with a layer of compost or vermiculite just a couple of millimetres deep.
Put the other container over the top to seal in moisture and warmth. Mine has holes in the top so I am also covering it with a polybag.
Make sure you label your seeds as all green seedlings look the same.
Stand your propagator in a sunny place. Just a couple of days and the seeds are beginning to grow.
